欠点があつた。 The conventional switch knob mounting structure includes a front protrusion having an engaging part on the front surface of the slider, and an elastically displaceable engaging part on the inner periphery of the cylindrical knob. There was one that completed the installation by fitting into the protruding part of the slider and engaging each other's engaging parts, but with this, the knob was cylindrical and had an elastically displaceable part, making it larger and making it easier to use other switches. When it is attached to a panel, etc., a large amount of mounting space is required in the knob portion, which makes the mounting work and mounting structure troublesome.

離脱するようなことはない。 24 is a knob made of aluminum die-casting, for example.
A protrusion 24b is integrally formed on the rear surface of the knob 24a, and the protrusion 24b has inclined surfaces 2 on the upper and lower rear surfaces, respectively.
It has a pair of engagement protrusions 24d provided with 4c. The knob 24 is attached to the holding part 22 of the slider 20 by first inserting the rear end of the protrusion 24b into the square hole 22a and abutting the pair of inclined surfaces 24c against the chamfered ends of the square hole 22a. let Next, when the knob 24 is pushed further backward, the hole end of the square hole 22a relatively rides up on the inclined surface 24c and further rides on the upper surface of the convex part 24d. During this time, the holding part half 22d is elastically displaced upward and downward by its own elasticity, but then the knob 2
4 moves rearward and the convex portions 24d respectively engage the engagement holes 22.
When the knob 24 falls into engagement with the slider 20, the knob 24 returns to its elastic displacement, and the knob 24 is attached and locked to the holding portion 22 of the slider 20. According to the mounting structure of the knob 24 and the slider 20, the knob 24 has a simple block shape and in this case has an elastic displacement part, unlike the conventional knob which has a cylindrical shape and has an elastic displacement part and is therefore large in size. Since it is provided on the slider 20 side, the shape of the area around the knob 24 and the holding part 22 can be reduced in size, and the mounting space to a panel 25, etc., which will be described later, can be reduced and the mounting work can be facilitated.
In addition, since the knob 24 is securely fixed to the slider 20 by the engagement between the protrusion 24d and the engagement hole 22c, the knob 24 will not come off from the slider 20 after attachment.

As shown in FIG.
Normally, both front sides of the slider 20 are in contact with the back surfaces of the contact plates 14a and 14b of the case 12 due to the energization of the coil 21, and the holding part 22 and the knob 24 is case 12
protrude forward. At this time, the lock pin 17 corresponds to the rear end of the heart-shaped cam portion 20a, and each sliding contact 23 makes common contact with the two front terminal plates 19 to close the space between them. In reality, the slider 20 is assembled before mounting the board 18, and the knob 24 is attached to the slider 20 assembled into the case 12.
It may also be assembled to In this way, push switch 11 is completed.

１２の上方変位を係止する。 Next, the structure for attaching the push switch 11 to the panel 25 in FIG. 2 will be explained. Panel 25
has a mounting hole 26, and the mounting hole 26 includes, in order from the top, an opening 26b having a side cut-and-raised portion 26a, a narrow hole 26c, a medium width hole 26d, and both side recesses 26e.
A wide hole portion 26f having a width is provided. Therefore, as shown by the two-dot chain line in FIG. 5, the engaging portion 13b on the front surface of the case 12 of the push switch 11 is inserted into the opening 26b of the mounting hole 26, and the engaging portions 14d on both sides are fitted into the wide hole 26f. The abutment plates 14a and 14b are brought into contact with the back surface of the hole edge of the middle width hole 26d by being inserted and protruded. Next, in this state, switch 1
1 is slid downward parallel to the surface of the panel 25 to the position shown by the solid line in the figure, the narrow width portion 13a of the engagement portion 13b is fitted into the narrow width hole portion 26c, and both side engagement portions 14d The recesses 14c engage with the recesses 26e on both sides of the wide hole 26f, respectively. At this time, the upper surface of the engaging part 13b is located at the same level as or slightly below the lower edge of the opening part 26b, and then
is bent from the two-dot chain line position to the solid line position in FIG. 5, and is brought into contact with the upper plate portion 13 of the case 12 to lock the case 12 from upward displacement.

取付け取外しを行ないうる。 Therefore, the switch 11 includes the engaging portion 13b, the narrow width portion 26c, the engaging portions 14d on both sides, and the recessed portions 26 on both sides.
It is mainly locked in the front-rear direction and left-right direction by each engagement e, and it is locked mainly in the vertical direction due to the contact between the upper plate 13 and the cut-and-raised portion 26a, and is firmly attached and fixed to the panel 25. If you want to remove the switch 11, bend the cut-and-raised part 26a in FIG. good. Therefore, the push switch 11 and the panel 25
can be installed and removed with one touch without the need for any screws or the like.

7 is a groove on one side of the heart-shaped cam portion 20a (not shown) while being rotated about the hole 16d of the spring plate 16.
When the slider 20 is guided relatively to the right side of the cam portion 20a in the figure and the pushing force of the slider 20 is released, it finally comes into contact with the engaging portion 20d of the cam portion 20a due to the bias of the coil spring 21. engage. As a result, the slider 20 is positioned, and each sliding contact 23 commonly switches into contact with the two rear terminal plates 19 to close the space between them. Subsequently, when the rear pushing force that pushed and slid the slider 20 further in the direction of arrow D is released, the lock pin 17 is released from the engagement with the heart-shaped cam portion 20a and passes through the side groove (not shown) as shown in the figure. At this position, the slider 20 also slides back to the illustrated position due to the biasing force of the coil spring 21, returning to its original contact switching mode.

の特長を有するものである。 As mentioned above, according to the switch knob mounting structure of the present invention, the knob can be simply shaped into a block, so the knob itself can be made smaller while maintaining its rigidity, and the switch can be further mounted on other panels, etc. The installation space around the rear knob can be reduced to simplify the installation work and mounting structure, and in addition, the projection can be easily press-fitted into the cylindrical body because an inclined surface is formed on the rear surface of the projection. In addition, since the knob and the slider are firmly attached by the engagement between the engagement hole and the engagement protrusion, it is possible to reliably prevent an accident in which the knob comes off after attachment.
